Sales tax = 7%.
Step-by-step explanation:
Let x be the percent of sales tax.
We have been given that Lisa buys a television for $4185. The sales tax is $292.95.
We need to figure out x such that x percent of 4185 equals to 292.95. Let us represent this information in an equation.
Let us multiply both sides of equation by 100.
Therefore, sales tax is 7%.
Let us cross check our answer by calculating 7% of 4185.
We can see that 7% of 4185 is 292.95. Hence, sales tax is 7%.
